JOHN D. HARVEY, OF SALINAS, CALIFORNIA.

LlNOTYPE-MOLD ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 625,445, dated May 23, 1899.

Application filed January 26, 1899. Serial No. 703,486. (No model.)

To all whom it may concern:

Be it known that I, JOHND. HARVEY, a citi zen of the United States, residing at Salinas, county of Monterey, State of California, have invented an Improvement in Linotype-Mold Adjusters; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to improvements in machines of that class known as linotype or line-casting machines, in which lines of matrices are assembled and the metal afterward cast against them to form a complete line of type.

My present invention consists in a means for adjusting at one time and with one change the length and width of the line to be cast by a small change in what is termed the liner without changing the mold proper.

Referring to the accompanying drawings, Figure l is a perspective view of the mold, showing the adjusting-liner. Fig. 2 is a view of the liner removed and the permanent end with which it is interlocked when in position.

In the use of the linotype -machines the matrices when placed to form a line of type are brought into line with an open space or channel through which the molten type is delivered to cast the line of type. As usually constructed the mold has a channel of this description of a fixed width, and any changes in the width and size of the line to be cast necessitate the removal of the mold and the insertion of another and expensive mold having a different width of channel and liner, all of which is troublesome and expensive. As now used a different and an expensive mold is necessary for each size or thickness of line needed, while with my device one mold will make all sizes and thicknesses of lines by simply changing the liner.

In my device the mold A is made with an open slot or channel, of which the part B represents the channel through which the molten metal passes to fill the matrices and form the line of type. The length of this channel is limited by the permanent stop 0 at one end and the movable or adjustable stop D, which forms the opposite end. The stop D has the dovetailed tapering tongues E formed transversely upon its upper and lower surfaces, and these dovetailed tongues fit into correspondingly-shaped grooves made transversely in the upper and lower surfaces forming the interior of thechannel, in to which this liner is to be fitted. By making the dovetailed tongues and grooves slightly tapering they interlock firmly when the liner is in place, and when the liner is to be removed it is only necessary to startit, when it will easily slip out in the line of the tongues and grooves.

The parts are all looked in place when secured together by screws F and G, which pass through the upper part A of the mold and screw into the lower part. The shank of the screw G passes through a slot H, made in the end of the liner and parallel with the dovetailed tongues, this slot being open at one end, so that when the screws have been properly loosened the liner can be pushed into place, the slot H slipping over the shank of the screw until the liner is seated, after which the screws F and G are turned down to lock the parts.

The liner'D has ashoulder formed, as shown at d, at the junction of the thickest portion, which fills the channel in the mold, and the thinner portion D, which extends over the open channel.

The permanent end piece C has dovetailed tongues extending longitudinally and fitting correspondingly-shaped grooves made in the parts A and A of the mold, so that this permanent part 0 can be slipped in until its inner end abuts against and on the full-width lip of the end of the part D of the liner and locks it as follows: The inner end of the part 0 has an angular depression 0, into which the lip on the end of the part D of the liner passes. In the center of the abutting portion of the part 0 is a groove 0', and this is engaged by a tongue (1, projecting from the lip on the end of the part D of the liner, so that after the liner has been slipped into place by means of its tongues and grooves the part 0 is pushed inwardly along the lines of its tongues and grooves, which are at right angles with the liner, until the tongue d and groove 0' have become engaged, and this serves to lock this end of the liner.

In order to allow the part 0 to be moved backward and forward su fiiciently to lock and unlock it in engagement with the end of the liner, the opening or hole I, through which the screw F passes, is elongaged sufiiciently so that when the screws F and G have been loosened for the purpose of removing or changing the liner the part 0 is first retracted lengthwise until the tongue and groove d a have been disengaged, the length of the oval slot I allowing of this movement. It is then only necessary to retract the liner transversely to remove it from the mold A A and another one can be inserted having any variation in the length or size of the opening B which may be desired. By this construction I am enabled to cast any size of slug or bar of type from the smallest to the largest by simply changing the liner instead of as now having to use a difierent mold for each diiferent size of type and line desired.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a mold of a linotype-machine, of a removable and adjusting liner having a reduced extension from one end adapted to project over and form one wall of the opening for the passage of molten metal to the matrices. V

2. The combination with a mold of a linotype-machine, of liners adapted to form varying casting-channels said liners having a reduced extension from one end forming one wall of the opening for the passage of molten metal to the matrices, and having a shoulder at the junction of said extension with the body, and means for locking the liners into the molds.

3. In a linotype-machine, a mold, in combination with a liner having one portion which is adapted to fill the channel in said mold and another portion adapted to only partially fill said channel, and a shoulder at the junction of the two portions.

4. In a linotype-machine, a mold, in combination with a liner having portions of unequal thickness one of said portions adapted to fill the channel in the mold and the other portion to partially fill and form a wall of said channel, and a tongue-and-groove connection adjacent faces of the channel.

and a liner in another portion of the channel and forming with the stop the opening for the passage of molten metal, said liner hav ing an extension from one end reaching to and adapted to lock with the stop.

6. A linotype-mold having upper and lower sections with a horizontal channel between the two, screws by which the two parts are locked together, and a liner adapted to fit and fill one portion of the channel having a thinner extension projecting over the remainder and forming an opening for the passage of molten metal to the matrices, transverse tapering tongues and grooves in the adjacent faces of the liner and the interior of the channel, and a slotted opening to fit the screw-shank at one end whereby the liner may be introduced.

or removed transversely, a permanent piece guided and movable at right angles with the movement of the liner and interlocking tongues and grooves by which said piece is caused to engage and hold the end of the liner after the latter has been inserted.

7. The two-part linotype-mold having the locking-screws, a channel formed between the two parts, a liner slotted to fit over one of the screws, tongues and grooves formed transversely in the adjacent faces of the liner and the interior of the channel whereby the liner is seated therein, a reduced extension of the opposite end of the liner whereby the size of the casting-channel is regulated, a longitudinally movable and guided permanent piece having an elongated slot fitting over the screw by which the opposite ends of the two parts of the mold are held together and interlocking tongues and grooves whereby said piece is caused to engage with the adjacent reduced end of the liner.

In witness whereof I have hereunto set my hand.
